It will see the remaining superheroes try to bring the missing ones back

However, soon later Ant-man is banging on the Avengers' door, seemingly not missing.

In October 2018, before the title was released, Mark Ruffalo allegedly "gave away" the title of the upcoming film during an appearance on the Jimmy Fallon show.

Ahead of the show airing, Mark tweeted: ‘@JimmyFallon, I trust that you will cut my spoiler slip on the show tonight. That was “off the record” homey. Please don’t get me in trouble with Marvel (Barry) again. DM me back. M.’
